Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a ...

Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists created an atomic circuit that may help quantum computing become a reality.

Quantum computer circuits can only operate at temperatures close to 0 Kelvin (absolute zero), and the way power is supplied must be carefully controlled to limit the effects of interference ...

Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum circuit capable of basic calculations and ...

For the first time, a superconducting circuit has passed a Bell test, the premier test in physics to confirm a system’s quantum behaviour. These circuits are used in quantum computers, and this ...
